So I took advantage of the Quidco/O2 deal and got myself an iPad SIM... which i also intend to use for O2 Priority :)
I have received the O2 SIM, chucked it in my unlocked iPad (usually uses a GiffGaff SIM) and went through the Settings>MobileData>ViewAccount and registered an account, card and paid £2 for 200mb for 24hrs on-off.
It was accepted but nothing really happened. My iPad is showing O2 signal and 3G but doesn't actually connect to the internet. I have restarted the iPad several times and it's been an hour since I first registered and topped up the SIM.
I've also tried putting the number (i.e. the "Mobile Data Number" for ipads) into the O2 Priority app and click "send code" and I haven't received anything.
Oh, and I went online and tried to register there. I Got as far as an activation PIN being sent to my other phone and enetered that... then nothing!
What have I done wrong?!
